Answer: 2

Solution: The greatest common factor of two numbers is defined as the largest number that divides both numbers into whole numbers (i.e. divides the numbers evenly).

The easiest way to find the G.C.F. in this case is to begin by listing the factors of the smaller number:

Factors of 70: 70, 35, 14, 10, 7, 5, 2, 1

See if 70 divides 458 evenly (it does not), then 35 (again, it does not), and so on...until we find a factor of 70 that is also a factor of 458. We find that 2 is the largest such number.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials
